Abstract
Coronavirus is the most serious problem facing the world nowadays. CoV is derived from the word ‘corona’ meaning ‘crown’ in Latin. It causes a range of human respiratory tract infections varying from mild cold to severe respiratory distress syndrome. The COVID-19 epidemic started from Wuhan city of China at the end of December 2019 and since then spread rapidly to Thailand, Japan, South Korea, Singapore and Iran in the initial months. This was followed by wide viral dissemination around the world including Spain, Italy, USA, UAE and the UK. The WHO declared the COVID-19 outbreak as a pandemic.
COVID-19-associated coagulopathy is common in patients with COVID-19, causing high rates of thrombotic complications that increase the morbidity and mortality.
Critically ill COVID-19, especially complicated by bedridden, obesity and other infection, is considered a risk factor for VTE, a combination of DVT and PE. The potential mechanism of VTE in COVID-19 is unclearly identified but is contributed by Virchow’s triad: hypercoagulability, stasis and endothelial injury.
DVT is a medical condition that occurs when a blood clot forms in a deep vein. These clots usually develop in the lower leg, thigh, or pelvis, but they can also occur in the arm. DVT can happen to anybody and can cause serious illness, disability, and in some cases, death. However it is preventable and treatable if discovered early.
